Worm Drive Index Head

This Sherline index head has been modified to have a worm and 45 notch worm wheel giving 8 degrees per revolution. It has been fitted with interchangeable detents which aid in indexing in half and third degree increments. It can also have the work lifted and locked out so as to be able to use the original indexing detent which renders 5 degree increments (this is normally locked out with a small brass block except when in use) so that you can choose between the speed and convenience of the 5 degree notch type indexing or the slower but more versatile worm indexing which offers a huge variety of options. The index head fits and mounts anywhere the original index head is used.
